What is biophysics?

 
  Biophysics is a branch of the sciences which applies chemistry and physics to the study of living organisms. For example, a biophysicist might explore cell signaling, in which cells transmit chemicals to each other to stimulate various responses. This field is extremely varied, with a number of applications, and new topics in biophysics are constantly being developed and discussed by researchers and other professionals in the field.
Biophysics is an interdisciplinary field which applies techniques from the physical sciences to understanding biological structure and function at the molecular level. In simpler terms we use a range of scientific techniques to try to understand what macromolecules like DNA, proteins, fats and sugars look like, and how they interact to form the biological systems around us. Plants, animals and even seemingly simple organisms like bacteria and archae consist of complex biological networks of chemical signals and molecular interactions, which enable them to do such things as move, respire or reproduce. Biophysics is a varied field which draws on biology, physics, chemistry, mathematics, engineering, genetics, physiology and medicine, all with the aim to understand these systems using experiments or theoretical and computational modeling. It is also a young science and is still rapidly developing - bionanotechnology and biosensors are just some of the latest fields to emerge in the last few years.
